Application led August 6, 1918. Serial No.A 248,571.

TJ all whom t may concern.'

Be it knownv that Roscon B,.KENDIG, late a citizen of the United-States, residing vat No. l Hawthorne Ave., Port Chester, New York, deceased, did invent certain new and useful Improvements in Car-Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, forming part of this specification.

This 4invention relates generally Ito railway car truck construction and more particularly tol a new and improved spring and equalizer` arrangement for yieldingly supe port-ing the truck frame upon the journal boxes.

The principal objects-of this invention are, to arrange the springs and equalizers so that they will in no wise interfere lwith the free inspection, repair and adjustment of the brakes and brake rigging associated `with the truck; further to provide guides for y the journal boxes, so that the same are maintained in true vertical positions, free from lphysical contact with the pedestals except at such intervals when the brakes are applied., and further, to provide improved means for connecting the endsof the semi;- ellip'tic springs and the rigid equalizers,

such means preventing lateral displacement of the associated parts.

lVith the foregoing and other objects in view, this invention consists in certain novel features of construction and arrangement of parts, hereinafter more-fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the side portion of a six wheel truck frame with which the spring equalizer arrangement is associated;

Fig'. 2 is a side elevational view of the truck frame with-the spring and equalizer arrangement applied thereto;

Fig. 3 is an enlarged vertical section taken approximately on the line 3-3 of Fig. 2;

Fig. 4 is a detail view partly in section showing the end of one of the semi-elliptic springs positioned on the end of one of the rigid equalizers. j

Referring by numerals to the accompanying drawings, 10 designates the wheel piece of a truck frame, the latterbeing preferably of integral construction and provided with the usual pairs of pedestal jaws 11.

Arranged vbetween these pairs of pedestal jaws are journal boxes 12, the same con- 4 --taining the usual bearings for the ends of the wheel carrying axles 13.

The wheel pieces 10 are preferably hollow and of box-like construction in cross section, the bottom wall of each wheel piece being cut away at points between the pedestal jaws for the accommodation `of, the journal boxes as the same move upwardly during service. The outer wall of each wheel piece is .cut away at suitable points to permit the ready insertion or removal of the rigid equalizer members and springs coperating therewith.

Mounted on each ljournal box 12 'is' a block or bracket 14, preferably of cast metal, the same being substantially U-shape in cross section and serving as a support for one of the rigid equalizer members 15. These equalizer members are preferably cast and seated in said members at or near the center thereof is a transversely disposed pin 16, the end port-ionsl of which project beyond the sides of the equalizerand'rest in suitable bearings 17, which 'latter are formed in the upper portions of the side walls of the block or bracket 14.

The outer wall of'each block'or bracket 14 is extended-upwardly a short distance beyond the bearing for the pin 16 and the side edges of this upwardly projecting portion bears directly against the peripheries of rollers 18, which latter are journaled on pins or bolts 19, the latter being seated in the outer wall of the wheel piece 10.

The side edges ofthe upwardly projecting portion of the block or bracket 14 are parallel so that as said block and the jour-G? nal box supporting the same move vertically, said journal box -is held to move in a true vertical position and without any f tendency to rotate about lthe axle. and thereby bind or bear with heavy pressure against the associated pedestal jaws.

The outer ends of the outer or end pair of rigid equalizers 15 are provided with hooks upper ends of which bear directly against the underside of the end portions of the wheel piece l0.

Bearing on the upper portion of the wheel piece and preferably against the underside of the top plate thereof are semielliptic springs 24, the same being disposed between the rigid equalizers and the ends of these springs bear directly upon both ends of the'middle equalizer and the inner ends of the outer or end pair of equalizers.

As illustrated in Fig. 4, the ends of the springs 24 are bifurcated as 25 in order to receive lugs or tongues 26 which are formed on the ends of the equalizers 15. This particular construction maintains 'the ends of the springs 20 and equalizers 15 in proper assembled relation and prevents lateral displacement of the parts.

A spring and equalizer arrangement constructed as herein disclosed is yielding and resilient to a high degree and b providing guiding means for the journal boxes while the same move vertically between the pedparting estal jaws, said boxes are normally maintained out of physical contact with said pedestal jaws, and they are eEectually held against tendency to rotate about the axles.

It will be readily understood that minor changes in the size, form and construction ofthe various parts of this improved car truck can be made and substituted for those herein shown and described, without defrom the spirit of the invention, the scope of which is' set forth in the appended claims.

What is claimed is:

l. rflue combination with a car truck, its' journal boxes and pedestal jaws, of means for yieldingly supporting the car truck u on the journal boxes, and means indepen ent of the pedestal jaws for guiding the journal boxes during their vertical movement, said means comprising rollers journaled on the truck frame above each journal box and a member extending upwardly from each above each journal designated by wheel piece, wheel piece,

journal box and normally bearing against said rollers.

2. The combination with a car truck, its journal boxes and pedestal jaws, of means for yieldingly supporting upon the journal boxes, and means independent of the pedestal jaws for normally holding the journal contact with said jaws, said means comprising rollers journaled on the truck frame box and a member extending upwardly Jfrom each journal box andvnormally bearing against said rollers.

3. The combination with a car truck, its journal boxes and pedestal jaws, of equalizer means for yieldingly supporting the car truck upon the journal boxes, a member projecting upwardly from each journal box, which member supports a ortion of the equalizing means, and guiding rollers on the truck frame for each upwardly projecting member.

4. The combination with a car truck, its journal boxes and pedestal jaws, of means Afor yieldingly supporting the car truck upon the journal boxes, an upwardly probox, said member serving as a support for a part of the truck supporting means, and a pair of guide rollers for each journal box supported member. y

5. ln a car truck, a wheel piece provided with pedestal jaws, a journal box positioned between said jaws andadapted to move vertically, a member carried by and projecting upwardly from said journal box into the and rollers journaled on said which rollers serve as bearmgs for the member projecting upwardly from the journal box.
